NsLookup.io VS ViewDNS.info

I see myself expanding nslookup.io into a wider range of web-based networking tools. More like an integrated web app where you can explore internet infrastructure than a collection of individual tools. Source: 12 months ago

I am shocked the website is IPv4 only and a check I did on nslookup.io shows petition.eu points to an A record 35.239.211.251, hosted by Google. I am sure Google can provide an IPv6 address if requested, so I do not know why the operator of petition.eu has not requested. Source: about 1 year ago

Well, whois command is your friend, if you have a domain name. If you have a ip address, you have to work more on it, anyway you can try some reverse DNS or other tool that you can find here: https://viewdns.info/ or you are... Source: over 1 year ago
